Just slightly witty and i guess that was a compliment then, i was off by 21 years...
The guy I work for has been operating this Grease Monkey since 1995, he fully bought it in 2004 when it was making $40,000 a month. He now makes $80,000+ a month and his operating costs are about $28,000 a month including labor. $52,000 a month in capital sounds pretty dang good to me and with a 78% return rate on all customers he is second in the nation for Grease Monkey's, even though he price gouges on everything.
And if I were your buddy and found you were blabbing about my business on a public forum, you would be looking for a new job. Be careful what you wish for.
